Bound
The opposite of rebound. The inward travel of the piston rod in a shock absorber.
Bound Electron
An electron whose orbit is near the nucleus of an atom and is strongly attracted to it.
Boundary Layer
The thin layer of air along the inner walls of an intake port.
Bourdon Tube
A curved tube that straightens as the pressure inside it is increased. The tube is attached to a needle on a gauge, that senses the movement of the tube and transmits it as a pressure reading.
Bowden Cable
1. A wire cable inside a metal or rubber housing used to regulate a valve or control it from a remote place. 2. A small steel cable inside a flexible tube used to transmit mechanical motion from one point to another.
Bowtie
The Chevrolet logo. Numerous dress up components for a Chevrolet engine compartment feature this logo, and so do all sorts of exterior restyling components, from license plate frames to a Bowtie-shaped exhaust tip.
Box Stock
Standard, conforming to OEM specifications.
Boxer
A horizontally opposed engine.
Boyle's Law
Robert Boyle (1627 - 1691 ) In 1662 He published a principle that later was named after him Boyle's Law states that the volume of a given mass of gas (the temperature being constant) varies inversely to it's pressure; or that the pressure and volume of a gas are inversely proportional.
